Understanding the Difference Between Refrigerant and Coolant
Defining the Terms
Refrigerant and coolant are two terms often used interchangeably in the context of cooling systems, but they have distinct meanings and functions. A refrigerant is a substance used in refrigeration cycles to transfer heat from one location to another, while a coolant is a substance used to regulate the temperature of a system or engine.
The primary function of a refrigerant is to absorb heat from a cold source and release it to a hot sink, thereby cooling the system. This process is known as vapor-compression refrigeration, where the refrigerant changes state from liquid to gas and back to liquid as it absorbs and releases heat.
On the other hand, a coolant is used to regulate the temperature of an engine or system by absorbing and releasing heat. Coolants are typically used in automotive, industrial, and aerospace applications to prevent overheating and damage to equipment.
